  25 For communication with Exchange 2007/2010 Web Server/Web Services:
  26
  27 1) Autodiscover (HTTPS POST request). With redirect support. XML content.
  28 1.1) DNS SRV record _autodiscover._tcp.<domain> may also be resolved.
  29 2) Availability Web service (SOAP = HTTPS POST + XML) call.
  30 3) Out of Office (OOF) Web Service (SOAP = HTTPS POST + XML) call.
  31 4) Web server authentication required - NTLM and/or Negotiate (Kerberos).
  32
  33 Note: ews - EWS stands for Exchange Web Services.
  34
  35 It will be able to retrieve our Calendar information (FreeBusy, WorkingHours,
  36 Meetings Subject and Location, Is_Meeting) as well as our Out of Office (OOF) note
  37 from Exchange Web Services for subsequent publishing.
  38
  39 Ref. for more implementation details:
  40 http://sourceforge.net/projects/sipe/forums/forum/688535/topic/3403462
  41
  42 Similar functionality for Lotus Notes/Domino, iCalendar/CalDAV/Google would
  43 be great to implement too.
